This is an excellent set up, very well looked after. The housing was originally for the D800 but was converted by the Nauticam main dealer for the D810 (minor changes). It also has the Vacuum leak detection system.
Only reason for the reluctant sale is that I am interested in changing from Nikon to Canon (maybe). Seeing what interest is out there.
